CHARLES HENRY SCHADT, OF NEIV YORK, N. Y.

ANVIL.

Specificaton of Letters Patent No. 31,410, dated February 12, 1861.

To all whom 'it may concem:

Be it known that I, CHARLES H. SGHADT, of the city, county, and State ofNew York, have invented a new and useful Improvement in Anvils; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part of this specifioation, in which Figure 1represents a Vertical central section of my invention. Fig. 2, is ahorizontal section of the same taken in the plane indicated by the linem a: Fig. 1.

Similar letters of reference in both Views indicate corresponding parts.

Anvils are generally placed on solid wooden blocks or sometimes onbarrels or tubs filled with sand, and if such an anvil is used in theupper stories of a house every blow struck on it makes the housetremble, because the full force of the blow is transmitted through theanvil and its solid support to the floor. It has therefore been proposedto place the block of Wood which supports the anvil, on thick pads ofindia rubber or other elastic substance and by these means thedifficulty above alluded to has been remedied, at least to a certaineXtent. But another difficulty arises now; the anvil is liable to moveon the floor, so that it has to be replaced at short intervals.

To overcome all those difiiculties is the object of my invention, whichconsists in the arrangement of a stout spring, resting on the under sideof a rising and falling plate which supports the anvil, and which isacted upon from the upper' side by a series of light springs in such amanner that the force of the blow is counteracted by the stout springand that the recoil of this spring is counteracted by the light Springs.

To enable those skilled in the art to make and use my invention I willproceed to describe its construction and arrangement.

The anvil A is inserted into the cover B of the case C and its roundfoot, D passes through a plate E and through the guide plate F. Theplate E is forced up under the shoulder of the anvil by means'of a stoutspring G, which is wound around the foot of the anVil and which rests onthe guide plate F, and a series of light springs H are interposedbetween the loose plate E and the cover B of the case. A false bottom Ia short distance under the guide plate F pre- Vents the anVil fromsinking down too low if it is eXposed to extraordinary heavy blows.

Under ordinary blows the stout spring G is compressed and the action ofthe blows on the floor on which the case stands is thereby completelyabolished and on rebounding, the spring G fo-l'ces the plate E upagainst the light springs I-I and a jumping of the anvil or a motion ofthe case C on the fioor is t-hereby prevented.

It is obvious that this improvement is adaptecl with equal facility toanvils of different forms, and the form and shape of the case has to bealtered as occasion may require, but in all cases it is renderedperfectly practicable by my improvement to use an anVil on the upperfloor of a building just as well as on the ground floor.

Having thus fully described my invention, what I clailn as new anddesire to secure by Letters Patent is- The arrangeinent of the stoutspring G, rising and falling plate E and weak Springs H in combinationwith the case C and anvil A constructed and Operating substantially asand for the purpose described.
